That would be to easy Tim :laughing: on the dizzy part anyway, but then i would have to get a diffrent tach :thud: and the mechanical tach probably would not fit in the factory location,then i would have to drill a hole in the fire wall,and that just leads to other whileImAtIt's :laughing:Kevin-- RTFM!!:rolling:
The run-on with an MSD box is from the alternator backfeeding the MSD box and keeping it powered. They give you a diode to stop that from happening. I didn't have any problem with my Summit/Mallory box. And they also said it doesn't happen on all cars. If you'd just do the simple thing and swap to a mechanical tach you wouldn't have to worry..
I did RTFM :rolling: but it just did not make much sense to me :WTF
